Problems solved by technology

In use, a material to be processed is passed into and through the extruder barrel and is subjected to increasing levels of temperature, pressure and shear.
Unfortunately quantities of starch are not always desired in food products, for many animals, such as gorillas, dogs, cats, horses, humans and the like.

example 1

[0036]This example illustrates the use of a gum as a binder during extrusion of an animal feed having less than 4 weight percent starch. 5ZF1 Mazuri Wild Herbivore Diet Hi-Fiber meal (PMI Nutritional International, LLC of Brentwood, Mo.) having less than 4 weight percent starch was homogeneously mixed with approximately 5%, 3% and then 1% of a heat-settable gum in the form of Ticagel PF-80 (TIC gums, Inc. of Belcamp, Md.). 5ZF1 Mazuri Wild Herbivore Hi-Fiber has the following ingredients:

In the three runs, Ticagel PF-80 a pet food-grade kappa-carrageenan that forms a gel, was used. The dry mixture was homogeneously mixed and then ground in a Fitzmill® Grinder (The Fitzpatrick Company of Elmhurst, Ill.) through a 4 / 64 inch ...

example 2

[0040]5ZF1 Mazuri Wild Herbivore Diet Hi-Fiber meal (PMI International, LLC of Brentwood, Mo.) was mixed with approximately 10% of Ticagel 550 PT in a first run and 10% Guar 8 / 24 in a second run. (Both from TIC gums, Inc. of Belcamp, Md.). 5ZF1 contains less than 4 weight percent starch Both mixtures were homogeneously mixed and then ground in a Fitzmill® Grinder (The Fitzpatrick Company of Elmhurst, Ill.) passing through a 4 / 64 inch screen.

[0041]After grinding, the dry mixture was introduced into the extruder using the extruder setup as described in Example #2.

[0042]The ground dry mixture was mixed with water added at a rate of 0.43 lbs per minute at the conditioning section of the extruder. The addition of steam to the dry mixture formed a mash that had a temperature of about 208° F.

[0043]Additional water was added to the inlet of the barrel at the rate of 1.07 lbs / min. The screw was operated at a speed of about 515 RPM. The hot mash was cooked and sheared until the hot mash forme...

example 3

[0045]Different levels of a kappa-carrageenan gum (Ticagel PF-80) were tested as a binder with 5MG7 Wild Herbivore Diet (from PMI International, LLC of Brentwood, Mo.). 5MG7 Wild Herbivore Diet has the following ingredients:

The 5MG7 Wild Herbivore Diet was extruded (Wenger X-200, Wenger Manufacturing Co, Sabetha, Kan.) without a binder and produced particles that would not hold together.

Abstract

The present invention includes methods for producing an extruded food particle by extruding through an extruder having a screw within a barrel, a composition containing nutritional food components, essentially no starch and a gum in an amount sufficient to act as a binder once the composition exits the extruder. The present invention also includes extruded food particles that do not use starch as a binder.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]None.BACKGROUND OF THE INVENTION[0002]The present invention generally relates to extrusion of feed and food products. More specifically, the present invention relates to methods of extruding feed and food products that uses a heat-set gum rather than starch as a binder during extrusion. The present invention also includes extruded feed and food products that contain a heat-set gum as the binder and little, if any starch.[0003]Extrusion cooking devices have long been used in the manufacture of a wide variety of edible and other products such as human food and animal feeds. For example, large extruders have been used for many years for the production of dry chunk-type dog foods. Generally speaking, such equipment includes an extruder having an elongated, tubular barrel with one or two elongated, helically flighted, axially rotatable screws therein. A multiple-orifice die is normally attached to the outlet end of the extruder barrel and is th...
